  1. jQuery itself is just a library, and if you need it, you probably will have some custom javascript code (initializing jQuery plugins like sliders, carousels etc) in your custom scripts.js (app.js or whatever). So, the smartest way to include jQuery is to call it as a dependency for your custom script.
